The frame is quite a jigsaw, but follow instructions and it works well.  Obviously the construction is a trifle flimsy, but if you want a permanent structure, buy a glasshouse!!

Bought to protect plants through winter months while we were away, and again this worked well.  The only reason for a 4-start rating instead of 5-star was that a zip gave way during a windy period, so another means of closing the greenhouse had to be taken.

Good value for money.
